dce8d251c6 keymap: Remove virtual modifier mapping functions
These are not used anymore.

Drop the vfuncs and their implementations in the
broadway, x11, wayland and win32 backends as well.

25e9a54902 win32: Stop using MODx modifiers
The win32 backend is using GDK_MOD2_MASK for AltGr,
so define GDK_MOD2_MASK locally to keep this working,
but remove any mention of GDK_MOD3_MASK,...,GDK_MOD5_MASK.

cba75d8239 GDK W32: Handle CapsLock as part of the key shift level
Instead of using some kind of flawed logic about modifying a keypress result
when CapsLock is toggled, just add a CapsLock shift level (and all derived
shift levels, i.e. Shift+CapsLock and CapsLock+AltGr and Shift+CapsLock+AltGr)
and query Windows keyboard layout API about the result of keypresses involving
CapsLock.

Keysym table is going to be (roughly) twice as large now, but CapsLock'ed
keypresses will give correct results for some keyboard layouts (such as
Czech keyboard layout, which without this change produces lowercase letters
for CapsLock->[0,2,3,4...] instead of uppercase ones).

Keymap update time also increases accordingly.

33442d953d GDK W32: Special handling for VK_PAUSE
Similar to VK_DIVIDE, this key can't be mapped to a scancode by
MapVirtualKeyEx(). Googling suggests that this is a known bug.

5e6c1928b4 W32: Prefer the deadkey combinations that the OS uses
Pick the W32 API for possible deadkey+<something> combinations
and prefer these to other sources of deadkey combos.
Specifically, if W32 API supports at least one combo for a particular
deadkey, only use that data and do not attempt to do other, unsupported
combinations, even if they make sense otherwise.
This is needed to, for example, correctly support US-International
keyboard layout, which produces a combined character for <' + a>
combo, but not for <' + s>, for example.

This is achieved by stashing all the deadkeys that we find in
an array, then doing extra loop through all virtual key codes and
trying to combine them with each of these deadkeys. Any combinations
that produce a single character are cached for later use.

In GTK Simple IM context, call a new GDK W32 function to do a lookup
on that cached combination table early on, among the "special cases"
(which are now partially obsolete).

A limitation of this code is that combinations with more than
one deadkey are not supported, except for combinations that consist
entirely of 2 known deadkeys. The upshot is that lookups should
be relatively fast, as deadkey array stays small and the combination
tree stays shallow.

Note that the use of ToUnicodeEx() seems suboptimal, as it should
be possible to just load a keyboard library (KBD*.DLL) manually
and obtain and use its key table directly. However, that is much more
complicated and would result in a significant rewrite of gdkkeys-win32.
The code from this commit, though hacky, is a direct addition to
existing code and should cover vast majority of the use-cases.

52c7e07948 GDK W32: Cache multiple keyboard layouts simultaneously
This changes the group/level semantic.
Previously W32 backend used "group 0/1" to denote "AltGr OFF/ON"
and "level 0/1" to denote "Shift is OFF/ON".
Now "group" means "keyboard layout" and there can be up to 255 groups,
while AltGr and Shift are combined into a single level enum that
takes values between 0 and 4.
Unlike X, W32 doesn't do effective group overriding, meaning that
it will never tell the caller that a different group was actually
used (even for universal keys, such as Enter), because key symbol
table is completely fabricated and there's no point in trying to
save a few of kilobytes of RAM by not duplicating universal key
records for all groups.

Also contains many whitespace changes (tab elimination, fixed
indentation) and cleanup (axed a few global variables, these are
now accessed via the default keymap).

0a6ee5e2cf W32: Fix for commit 1f74f12d9, re-enabling decimal separator key
1f74f12d9 rendered entry of keypad decimal mark unuseable for
several national keyboard layouts, this commit amends that, at
least for W32, and makes GTK+ behave more or less the same way
W32 behaves.

The patch works like this:
- When typing the first character at the keyboard or when switching
  keyboard layouts, the decimal mark character will be cached in the
  static variable "decimal_mark" within gdkkeys-win32.c

- in case of WIN32, gdk_keyval_to_unicode() asks gdkkeys-win32.c for the
  current decimal_mark when converting GDK_KEY_KP_Decimal.

	timer during resizes/moves. Calls handle_stuff_while_moving_or_resizing().

	(gdk_event_translate): Drop unused return_exposes parameter.

	Handle WM_XBUTTONDOWN and UP messages (buttons 4 and 5).

	On WM_SYSKEYUP, generate a key release event also for just the Alt
	key.

	On WM_MOUSELEAVE, generate a leave event of type
	GDK_NOTIFY_ANCESTOR (and not UNKNOWN) if the mouse left a
	top-level window, and left the app completely.

	On WM_ENTERSIZEMOVE, set a flag, and start an interval timer that
	calls resize_timer_proc() at regular intervals. On
	WM_EXITSIZEMOVE, kill the timer.

	On WM_WINDOWPOSCHANGED, generate a configure event if necessary,
	and dispatch the main loop (by calling
	handle_stuff_while_moving_or_resizing()). Fixes #99540, idea by
	Herman Bloggs.

	* gdk/win32/gdkmain-win32.c (_gdk_win32_message_to_string): Handle
	also wintab messages.

	* gdk/win32/gdkwindow-win32.c (gdk_window_set_skip_taskbar_hint):
	Instead of using WS_EX_TOOLWINDOW, implement by setting/unsetting
	the window's owner. Fixes #118093, reported by Maxime Romano.

2003-07-25  Tor Lillqvist  <tml@iki.fi>

	* gdk/win32/gdkprivate-win32.h
	* gdk/win32/gdkglobals-win32.c: New flags _gdk_input_locale_is_ime
	and _gdk_keyboard_has_altgr.

	* gdk/win32/gdkevents-win32.c: Lots of changes. Most important
	ones detailled here.

	Code that has been ifdeffed out for a long time removed. Remove
	some really old doc comments that were left behind for some public
	functions, the official ones are in the X11 backend anyway. Change
	GDK_WINDOW_OBJECT() calls to GdkWindowObject casts. Reformat
	multi-line boolean expressions to have the operators at ends of
	lines.

	As mouse capture with SetCapture() indeed seems to work OK, no
	need to have the correspoinding macro USE_SETCAPTURE and ifdefs.

	Ifdef out the gdk-ping-msg stuff. I don't remember why it was
	needed at some time, and things seem to work fine now without
	(knock on wood).

	Ifdef out the search for some Latin locale keyboard layout being
	loaded. Not used currently, but might be needed after all, if we
	decide that we want to be able to generate ASCII control character
	events with a non-Latin keyboard.

	(assign_object): New helper function, handles the g_object_ref()
	and unref() calls when assigning GObject pointers.

	(generate_crossing_events): Also generate the GDK_NOTIFY_INTERIOR
	enter event when the pointer has moved to an ancestor window. Was
	left out by mistake.

	(gdk_window_is_ancestor): Renamed from gdk_window_is_child().

	(gdk_pointer_grab, gdk_pointer_ungrab): Implement the confine_to
	functionality, using ClipCursor().

	(find_window_for_mouse_event): Splice part of code into new
	function find_real_window_for_grabbed_mouse_event().

	(fixup_event, append_event, apply_filters): New functions, code
	refactored out from elsewhere.

	(synthesize_enter_or_leave_event, synthesize_leave_event,
	synthesize_enter_event,
	synthesize_leave_events,synthesize_enter_events): Also take a
	GdkCrossingMode parameter, in preparation to generating
	GDK_CROSSING_GRAB and GDK_CROSSING_UNGRAB events.

	(fixup_event, append_event, fill_key_event_string): New functions,
	code refactoring.

	(vk_from_char, build_keypress_event, build_keyrelease_event):
	Removed as part of dropping WM_CHAR handling.

	(build_key_event_state,gdk_event_translate): Call
	GetKeyboardState(), once, for each keyboard message, instead of
	several calls to GetKeyState() here and there.

	(gdk_event_translate): Fix bugs #104516, #104662, #115902. While
	at it, do some major refactoring, and some fixes for potential
	problems noticed while going through the code.

	Don't handle WM_CHAR at all. Only handle WM_KEYDOWN and
	WM_KEYUP. Don't need the state variables related to whether to
	wait for WM_CHAR or not, and whether the current key is
	AltGr. Remove lots of complexity. Thus don't need the
	use_ime_composition flag.

	Not handling WM_CHAR means dead key handling will have to be taken
	care of by GTK, but that seems to work fine, so no worry.

	Another side-effect is that Alt+keypad digits don't work any
	longer, but it's better to learn to use GTK's ISO14755 support is
	anyway.

	Be more careful in checking whether AltGr is involved. Only
	attempt to handle it if the keyboard actually has it. And
	explicitly check for *left* Control plus *right* Alt being
	pressed. Still, allow (left) Alt and/or (right) Control with AltGr
	chars.

	Handle keys using similar code as in the X11 backend. As we have
	built a keymap in gdkkeys-win32.c anyway, use it by calling
	gdk_keymap_translate_keyboard_state() to look up the keysym from
	the virtual key code and keyboard state. Build the key event
	string in exactly the same way as the X11 backend.

	If an IME is being used, don't generate GDK events for keys
	between receiving WM_IME_STARTCOMPOSITION and
	WM_IME_ENDCOMPOSITION, as those keys are for the IME.

	For WM_IME_COMPOSITION, handle all the Unicode chars returned from
	the IME, not just the first one.

	gdk_event_translate() is still quite complex, could split the
	message handler cases out into separate functions.

	On mouse events, when the mouse is grabbed, use
	find_real_window_for_grabbed_mouse_event() in order to be able to
	generate correct crossing events.

	No longer take a pre-allocated GdkEvent as parameter. Instead,
	allocate events as needed and append them to the queue. (This is
	different from how gdk_event_translate() in the X11 backend
	works.) This change made the code much clearer, especially in the
	cases where we have to generate several GDK events for one Windows
	message.  Return FALSE if DefWindowProc() should be called, TRUE
	if not. If DefWindowProc() should not be called, also return the
	value to be returned from the window procedure.

	(Previously, the interaction with gdk_event_translate()'s caller
	was much more complex, when we had to indicate whether the
	already-queued event should be left in the queue or removed, and
	in addition also had to indicate whether to call DefWindowProc()
	or not, and what value to return from the window procedure if
	not.)

	Don't use a separate "private" variable required to be pointing to
	the GdkWindowObject of the "window" variable at all times. Just
	use casts, even if looks a bit uglier.

	Notice destroyed windows as early as possible, and break out of
	the messsage switch.

	Use _gdk_pointer_root as current_window when the pointer is
	outside GDK's top-level windows.

	On WM_INPUTLANGCHANGE, set _gdk_input_locale_is_ime as
	appropriate, based on ImmIsIME().

	(gdk_event_translate, gdk_event_send_client_message_for_display,
	gdk_screen_broadcast_client_message): Implement client messages.
	Use a registered Windows message to pass GDK client messages. Note
	that the amount of user data is restricted to four bytes, as it is
	carried in the LPARAM. (The WPARAM is used for the message type
	"atom".)

	(real_window_procedure): Adapt for new gdk_event_translate()
	interface.

	* gdk/win32/gdkmain-win32.c (_gdk_windowing_init): Set
	_gdk_input_locale_is_ime initially.

	* gdk/win32/gdkwindow-win32.c: Use g_object_ref()/unref() instead
	of g_colormap_ref()/unref().

	(gdk_window_new): Made code a bit more like the X11 one, pretend
	to handle screens (although we just have one for now).

	* gdk/x11/gdkevents-x11.c
	(gdk_event_send_client_message_for_display,
	gdk_screen_broadcast_client_message): Document the user data
	limitation on Win32.

	* gdk/win32/gdkevents-win32.c (print_event): More complete enter
	and leave notify detail output.

	* gdk/win32/gdkkeys-win32.c (update_keymap): Make dead keys
	visible to GDK and GTK. Store the corresponding GDK_dead_* keysym
	for those, so that the GtkIMContextCimple compose tables will
	work. Deduce if the keyboard layout has the AltGr key, and set the
	above flag accordingly.
